5.4 Registers Tab
The Registers tab interacts with the registers and bits within the TMP108 device.
The Auto Read drop-down box configures polling of register contents. When Auto Read is Off, it is
necessary to click Read Register to fetch the contents of the current register. Read All Registers can be
used to fetch the contents of all registers at once. The Write Register button is greyed and disabled when
the drop-down next to the button is set to Immediate. Immediate mode triggers a Write operation each
time a register is modified. When Deferred mode is selected, the Write Register button is enabled, and
write operations will not be performed unless the Write Register button is clicked. These settings give the
user total control over I2C Bus activity, and enable individual transactions to be easily observed with an
oscilloscope, logic analyzer, or bus-sniffing device.
